I reinstalled the Chrome browser and it works now.
However I do have another problem. When I open Youtube or Netflix I can see the Chrome cast Icon on the top right of screen, but when I browse using the Chrome browser, this cast icon is not there.
Since I cannot Chromecast from my Tablet Samsung Tab3 7" SM-T210R is there any other way I can connect my Tablet to the TV. I have seen a MLT adapter which has a HDMI on one end and a micro USB on the other end but would this work with my tablet.
